Abstract

PURPOSE: To obtain a rubber composition for a tire tread of low fuel cost and with excellent braking performance, by adding a specified resin to a rubber component consisting of 1,2-polybutadiene and another diene rubber by means of two-step kneading.
CONSTITUTION: To 100pts.wt. raw rubber component consisting of 15W75pts.wt. amorphous 1,2-polybutadiene contg. 65W95mol% 1,2-bonding unit and 85W25pts. wt. another diene rubber contg. at least 40wt.% natural and/or polyisoprene rubber are added 40W70pts.wt. carbon black and 0.5W5pts.wt. resin of softening pt. 80W120°C contg. 3W6 phenol neuclei, obtd. by the polycondensation of a phenol with formaldehyde and/or methylolmelamine, to obtain a rubber composition. Then, the first-step kneading is carried out with addition of 40W70pts. wt. carbon black to 40W60pts.wt. said raw rubber component contg. at least 15pts.wt. 1,2-polybutadiene, and the second-step kneading with addition of the residual raw rubber component and carbon black, to prepare the rubber composition.
